STEAM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 422,622, dated March 4,1890.

Application filed July 19, 1889. Serial No. 318,060. (No model.)

To all whom it may concern.-

Be it known that I, LEWIs B. PHILLIPS, a citizen of the United States,residing at Diana, in the county of Lewis and State of New York,

have invented certain new and useful Improvements in Steam-Engines; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itap- IO pertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

I 5 This invention relates to certain new and useful improvements insteam-engines; and

it has for its object to generallyimprove upon the construotion,tocheapen, and at the same time render more efficient, durable, andserviceable in operation this class of devices.

The invention has for its further objects the lessening of friction andweight, the dispensing with the rocking arm, link, and lever heretoforeused, and the providing of a sim- 2 5 ple reversing-valve mechanism, bymeans of which the engine may be at any time instantly reversed orstarted when desired.

To the above ends and to such others as the invention may relate thesame consists in the peculiar combinations and in the novelconstruction, arrangement, and adaptation of parts, all as more fullyhereinafter described, shown in the accompanying drawings, and thenspecifically defined in the appended 3 5 claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters and figures of reference marked thereon, form apart of this specification, like letters 40 and figures of referenceindicating like parts throughout the several views, and in whichdrawings- Figure 1 is a side view of an engine constructed in accordancewith my invention, the

head of the steam-chest being removed. Fig. 2 is a section on line a: a:of Fig. 1. Fig. 3 is a section on line g y of Fig. 1. Fig. 4 is a sideview with parts broken away and the steam-chest and cylinder shown-winsection.

Fig. 5 is a detail perspective view of the rotary or reversing valve andits surrounding case, the valve being shown as removed from the case.Fig. 6 is a detail view of the vertical rotary valve and its case.

Reference now being had to the details of the drawings by letter, Arepresents the upright or frame of the engine, securely bolted to theupper plate B of which frame is the cylinder 0; The piston-rod (3 passesthrough a central hole in the bottom of the cylinder, and is connectedby means of the link or rod D with the transverse shaft D, which shaftcarries at one of its ends the pulley D from which power may betransmitted, as will be readily understood.

E is the steamchest, which is securely bolted upon one side of thecylinder, as shown, and is divided by means of a central partition Einto two compartments E and E 1 is a valve arranged to extendhorizontally 7o therein by means of a lever or handle 3, se

cured to the end of the neck or extension 4:, which is extended throughthe side wall of 7 5 the steam-chest. This valve is the reversingvalve.The shell 2 is provided upon opposite sides near its ends with openings5 for the passage of the steam.

The valve 1 is provided with ports 6 and 7, 8o whichextend directlythrough the body of the valve, the open ends of the ports registeringwith the holes 5 in the shell 2.

8 and 9 are ports in the valvel, which ports consist of grooves formedin the face of the valve and extend obliquely one-half the circumferenceof the valve, the ends of the grooves being at points upon the face ofthe valves at right angles to the ports 6 and 7, so that the entrancesto the ports will register with the holes 5 in the shell when the valvehas been given one-fourth of a revolution.

10 andll are inlet and exhaust pipes, respectively, the which pipescommunicate with the holes in shell 2, as shown. It will be seen that 5when the valve 1 has been turned so as to cause the ports 6 and 7 toregister with theholes in the shell 2 the steam from the inlet-pipe willpass directly through the port 7 into the compartment E of thesteam-chest, and at the same time the exhaust-steam will pass throughthe port 0 of the valve into the exhaust-pipe. \Vhen the valve has beengiven a one-fourth revolution, the steam will enter the port 8, and,following the same obliquely one-half way round the valve, will enterthe compartment of the steanrchest, while the exhauststeam will returnthrough the port 9.

12 is a rotary valve vertically placed within the steam-chest, the samebeing adapted to rot-ate within an aperture formed for its reception inthe central partition of the steam-chest, the sides of the valveprojecting upon either side into the chamber of the steam-chest. Thevalve 12 is provided with ports 13 and 11, which ports extend directlythrough the valve one above the other, the upper port 14 being extendedat right angles to the port 13, as is clearly shown in Fig. 6.

17 is a case or shell surrounding the valve 12. This shell is providedwith holes 15 and 16 upon four of its sides, these holes being placed insuch horizontal planes as to register with the ports 13 and 14c in thevalve when the said valve is rotated.

18 is a wabbling wheel secured upon the shaft D, and 19 is a yoke, thebifurcated arms of which are provided at their free ends withinternally-extended projections or points 20. The bifurcated arms of theyokeli) embrace the wabbling wheel, and the points 20 are fitted withinthe groove upon the periphery of said wheel. The upper end of the bodyof the yoke 19 is connected with the shaft 21, attached to the valve 12by a universal joint 22.

23 and 21 are steamways connecting the steam-chest with the cylinder atthe top and bottom of the same, respectively, as best shown in Fig. 4 ofthe drawings. These steam ways extend through the wall or partition,separating the steam-chest from the cylinder at such points as willinsure their entrance to the steam-chest, registering with the ports inthe valve 12 when said valve has been rotated to the proper point.

In operation we will suppose in the first instance that the handle hasbeen turned so as to cause the entrances of the straight ports (3 and 7in the valve 1 to register with the holes in the surrounding case. Thesteam will enter the chamber E through the pipe 10 and correspondingstraight port in the valve. The steam from this chamber will enter theport in the valve 12, which may be open-at the time-as, for instance,the lower one, which registers with the hole 15 in the shell surroundingthe valve. Passing through said port in the valve 12 the steamwill enterthe lower end of the cylinder C through the steamway 24, and acting uponthe lower face of the piston-head will force the same upward, and duringthe upward movement of .the piston the exhaust-steam in the upper partof the cylinder passes out through the steamway 23, which communicateswith the chamber E of the steam-chest through the open port in the valvecommunicating therewith and passes out through the exhaust-pipe 11. Theupward movement of the piston will through its connections with theshaft D cause the said shaft to revolve, and the piston 12 will byreason of its connection with the wabbling wheel upon the shaft be giventhe one-fourth revolution, thus closing the port in the valve whichadmits steam to the cylinder from the chamber E and opening the steamwayleading from the lower end of the cylinder to the chamber E The outletfrom the upper end of the cylinder to the chamber E is at the same timeclosed, and the inlet from the chamber E to the upper end of thecylinder is opened. The steam will then enter the upper end of thecylinder through the steamway opening thereto from the upper port in thevalve 12, and the exhaust-steam will escape through the steamway andopen lower port in the valve to the chamber E and thence through theexhaustport in the valve 1 and exhaust-pipe 11. By turning thereversing-lever 3 so as to impart a one-fourth revolution to the valve 1the straight ports 6 and 7 in said valve and the spiral ports Sand 9 areopened. The steam will thus enter the spiral port 9 and, traversing thesame, will enter the chamber E of the steam-chest, and will be suppliedto the cylinder through the ports in the cylinder 12, which wereformerly the exhaust-ports. The steam will be exhausted in this caseinto the chamber E and will pass to the exhaust-pipe 11 through thespiral port 8 of the valve 1, as will be readily understood.

It will thus be seen that by simply turning the reversing handle orlever 3 the course of the steam to the cylinder may be changed from oneto the other of the chambers of the steam-chest, and the engine thusinstantly reversed.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. In a steam-engine, a cylinder, a twochambered steam-chest, saidchambers serving alternately as steam and exhaust chambers, steamwaysconnecting said chambers with the cylinder, a rotary valve arrangedwithin the steam-chest and provided with ports, as described, andmechanism, substanbers, steamways connecting the said chambers in thesteam-chest with the interior of the cylinder, a rotary valve within thesteamchest having ports arranged to register with the steamways whenproperly rotated, and connections between the shaft and valve wherebysaid valve is rotated by the turning of the shaft, substantially asshown and described, and for the purpose described.
